Potential & Kinetic Energy

* Description/Instructions

In a closed system, the sum of the potential energy and the kinetic energy is a constant. When the potential energy (PE) increases, kinetic energy (KE) decreases and vice versa. The formula for potential energy is weight times height (w * h). The formula for kinetic energy is one-half mass times velocity squared (1/2mv2). The following problems are simple energy problems using the above information. You will need a calculator and scratch paper. Select the best answer from the given choices.
